Selected writing for general audiences (for a list of technical papers, see here)

For some years most of my writing appeared in my now-rarely-updated blog. Here are a few of my favorites.
- To the moon (the Apollo program, my father)
- Planetary placemats (understand the solar system in one picture)
- What is a dwarf planet? (it's like a real planet, only dwarfier)
- What's in a name? (who should get to be called a planet?)
- Lilah Brown's Planets (a moment which I liked so much it became the epilogue of my book)
- Haumea (the discovery of and controversy over the dwarf planet)
- Baby pictures (the discovery of Eris and the rest)
- There is something out there (the discovery of Sedna)
- A ghost of Christmas past (Haumea's secrets)
- Free the Dwarf Planets! (there are many many dwarf planets out there, so why do we only talk about 5 of them?)
My memoir of the discovery of Eris, the demotion of Pluto, and all of the real life that happened in between, is called "How I Killed Pluto and Why It Had It Coming", but really, it is a love story, to my wife, my daughter, and the solar system. Here are a few reviews
- LA Times
- The Man Who Made A Planet Vanish, Wall Street Journal
- The Man Who Demoted the Planet Pluto, Boston Globe
